“There will be recognisable elements from the Kercher case but the film is more of a mirror of the events that went on in the background – the media frenzy surrounding the story,” Latza Nadeau, an American correspondent in Italy since 1997, told The Telegraph.

In an interview with The Guardian, Beckinsale said the film is not about Amanda Knox. "That case is peripheral," she said. "This is not a whodunnit."

The film is directed by Michael Winterbottom and also stars Rush-star Daniel Bruhl as a struggling filmmaker and supermodel Cara Delevingne as a student at college.
